Composting toilets could help reduce demand on local water resources – Williams Lake Tribune

We researched composting toilets for the cabin and as an outdoor option while working around our Williams Lake property in the summer.

Recently this seemed like a good way to extend the use of our fifth wheel on our property since the black tank would quickly fill up with a full time occupant which would mean moving to a dump or hauling it in with a portable tank.

There are a number of options with two designs separating the urine from the solids which reduces compost drying time and a liquid product which could be used on our outdoor plants.

These units are quite portable which means they would be a good backup if we lost our water source for some reason in the house or had sewer issues.

Some communities in the United States see composting as a way to improve the lives of most of their citizens. The following came from supporters in Vermont.

“Flush toilets are the largest user of water inside the home, turning drinking water into waste water that is expensive and resource-intensive to purify. Wastewater Systems Nutrients are often dumped into water bodies where they contribute to nutrient pollution, harmful algal blooms and other adverse ecological effects.

Dry toilets can help us collect our “waste” nutrients to compost them safely and efficiently so we can grow plants and support local food sovereignty. Unfortunately, some state regulations stood in the way, requiring homeowners to send this compost to the landfill as trash. This is a waste of a resource and causes climate-damaging landfill methane emissions. On January 12, 2022, Bill H.586 was introduced, which will lead to regulations and best management practices to guide the on-site composting of human waste and the safe use of the resulting compost.

If the use of waste associated with food production is an issue, it can be safely used in forestry applications. The Regional District of Nanaimo produces approximately 7,500 tonnes of biosolids each year and uses it in forest fertilization and soil making programs. Biosolids have been shown to increase tree growth on nutrient-poor soils.

Another article describes how using the right equipment and techniques can produce a safe and useful product from human waste. You should have a properly constructed dedicated composter so that there are no leaks that could contaminate groundwater. It should not get wet and have plenty of ventilation. The best way to meet these requirements is therefore a rotating drum or barrel that rests on the ground. If you’re a do-it-yourselfer, there are plenty of sites on the web that give details on materials and construction. Otherwise, the authors say some hardware stores sell them starting at around $100.

As described in a previous article, British Columbia is looking at composting as one way to deal with animal carcasses that became a huge problem following last year’s floods. With the recent rise in gas prices, incineration options will be less desirable.
